IMPROVED SEWING-MACHINE FAN.

The Schedule referred to in these Letters Patent and making part of the same.

To all whoml Iit may concern:

Be it known that I, D. W. GLAssIE, of Nashville; in the county of Davidson, and State of Tennessee, have invented a. new and improved Fan; and I. do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the accompanying drawings, forming part oft-his specitica-tion.

My invention relates to a' device which may be attached to the balance-wheel A(if a sewing-machine, or in any suitable manner to an actuating-wheel driven by any convenient power, and is provided with fans, which may be caused simply'to rotate, or to have a compound motion, reciprocating and rotary.

The invention consists in the combination of nicchanical means for operating the fans, which will be more particularly specified hereafter.

.lhe same let-tels represent corresponding parts in the figures of the drawing.

A, Figure 1, is a large pulley,- grooved on its periphery, and attached by screw-shanked hooks, B, to the balance-wheel 0f a.sewing-machine, as illustrated in iig. 1.

.D is an auxiliary pulley, which receives motionby a stI'a-pfi'ox'n A, :ind drives the fan-mechanism.

C is a suitable bed, with flanges fj, whereby the device may be attac-lied to a table, bench, or other article.

c c are pillow-blocks, in which are located the bearings ofihe shaft E, of the said pulley D.

On the right-hand end of said shaftI is placed a bevelgear, F, which has a stud, h, on its plain side.

The uprigl'it shaft G passes through a curved snpport, H, and turns on a hearing in the bedG.

On the .lower end of this shaft is a bevel-wheel, I, which gears in the bevel F, and is rotated by it.

The wheel'I is sustained in gear with F by a inovable shoulder, whereby it may he let down and allowed to rest on the hed C.

lhe wheel F also movable, and is taken otf and reversed on its Shaft, for a purpose hereafter mentioued.

J J represent fans, which are placed upon the top of shaft, and are rotated by the shaft G, which rcvolves them in a horizontal plane.

Figure 2 represents a pitnian, O, attached to a pin, 71, on the plain side of the bevel-wheel F, which has been reversed on its shaft E, and disconnected from the wheel I. At its upper end it is attached to the fan L, which swings loosely on a pin, 2.

As the crank O is reciprocated, by the rotation of the wheel F, it vibrates the fan L in a vertical plane.

lVith this apparatus a lady can operate the sewingmachine and fan herself simultaneously, without being sensible ofthe greater exertion o f power which she is required to make.

Having new described all that is necessary to make my device understood,

What l esteem as of my invention, and desire to protect by Letters Patent, is-

1. Lhe combination of a pulley, A, attached to the balance-wheel ot'a sewing-machine, with pulley D, shaft 1l,bed C c e, bevel-gearsF I, support H, and shaft G, all arranged to operate a fan, J J, in the manner described. Y

2. The combinationof said pulleys Aand D, located as described', with the bevel F, reversed, the crank O, crank-pin 71, sulmorting-shait G, all arranged to swing 'the fan L on its pivot in a vertical plane, as shown and described.
